Abstract: A method for using the quantity of heat output from an extrudate during a cooling operation in an extrusion process, wherein a fluid, in particular air, is guided along the extrudate and/or through the die counter to an extrusion direction, at least some of the heat from the extrudate and/or the die is transmitted to the fluid, the heated fluid is supplied from a first sub region of a process chain, comprising at least one die, a calibrating and cooling device and a take-off apparatus, via a connecting region, preferably consisting of at least one connecting pipe, to a second sub region of the process chain, comprising at least one suction apparatus. In the connecting region, an extraneous fluid can be added to the heated fluid in order to reduce the actual temperature of the heated fluid at least below a predetermined maximum value before said fluid is supplied to the second sub region of the process chain.

Abstract: The invention relates to a method for blocking roaming steering mechanisms. According to said method, a foreign cellular device (3), e.g. a cellular telephone, is registered with nationally visited radio network (2) when the foreign (1) and the national cellular network operator have concluded a roaming agreement on mutually debiting cellular services. The invention is characterized in that an anti-roaming steering server (5) installed in the nationally visited cellular network (2) identifies manipulated error messages (14) and selectively manipulates the registration process (8) of foreign mobile users by adequately influencing signaling processes.

Abstract: A method for informing a subscriber of a mobile telephony network about incoming calls while the mobile telephone of the subscriber is switched off or is not connected to the mobile telephony network. The notification takes place via the mobile telephone of the subscriber as soon as the mobile telephone has re-registered itself in the mobile radio network, and the message including at least the call number of the missed caller. In the event of a calling line identification restriction (CLIR) from the caller, a message is automatically produced and sent to the caller, by which means the caller is prompted, by a dialogue, to temporarily release the call number transmission for the call, such that the call number of the caller can be communicated to the subscriber.

Abstract: The invention relates to a method for delivering a short message in a mobile communications system, in which the short message sent from a mobile station is received by an SMS-Service-Centre, SMS-C, and forwarded to a corresponding recipient, wherein the SMS-C is addressed by means of an SMS-C address in the mobile communications system. The invention is distinguished by the fact that an SMS-C address recognized as erroneous is corrected on the part of the mobile communications system, and the delivery of the short message is continued with the corrected SMS-C address.

Abstract: The invention relates to a method for setting up a mobile radio connection to a mobile station (MS) in a cellular mobile radio network. According to said method, each cell of the mobile radio network can be identified by an identification character and a plurality of cells form a localisation area of the mobile radio network. In order to localise the mobile station (MS) inside a localisation area, paging is regularly carried out from a switching centre (MSC) in pre-definable time intervals, and a first mobile radio connection to the mobile station (MS) is set up by the paging, whereupon a paging response message is generated from the mobile station (MS) and transmitted over the existing first radio connection.

Abstract: An apparatus for developing radiation-sensitive, exposed printing forms into printing plates is disclosed. The apparatus has a developer pan in which a developer bath 2 is situated. The individual printing form runs through the developing station of this apparatus in a running-through plane. On both sides of the running-through plane there are a first pair of transport rollers, two brushing rollers with their counter-rollers and a second pair of transport rollers at the end of the developing station. Arranged between the first pair of transport rollers and the first brushing roller with its counter-roller, on the underside of the running-through plane, are guide rollers. A closed vessel, filled with developing solution, is connected via a developer circuit and a pump to the developer bath. In the vessel there are a temperature sensor and a measuring electrode for the electric conductivity of the developing solution.
